CHARLES LEROY, OF DAYSVILLE, NEW YORK, ASSIGNOR OF ONE-HALF TO .GRANT J. OALKINS, OF SAME PLACE.

POWDER-DUSTER.

SPECIFICATION forming part of Letters Patent No. 544,735, dated August 20, 1895.

Application filed March 19, 1895. Serial No. 542,355. (No model.)

To all whom it may concern:

Be it known that I, CHARLES LEROY, of Daysville, in the county of Oswego, in the State of New York, have invented new and useful Improvements in Dusters, ot' which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to improvements in dusters particularly applicable for discharging poison upon vegetation, and has for its object the production of a device which is readily manufactured and repaired and is capable of continued practical operation; and to this end it consists, ess'entially,in the general construction and arrangement of the parts of the dus'ter, all as hereinafter more particularly described, andpointed out inthe claims.

In describingthis invention reference is had to the accompanying drawings, forming a part of this specification, in which like letters indicate corresponding parts in all the views.

Figure l is a top plan of my improved duster, its blower being shown by full lines as expanded and by dotted lines as collapsed. Fig. 2 is a vertical section taken on line 2 2, Fig. 1, the parts being shown in their position assumed when the blower is collapsed. Fig. 3 is a horizontal section taken on line 3 3, Fig. 2, the blower being shown as expanded; and Fig. 4. is a transverse section taken on 1in 4 4, Fig. 2.

A represents a supply-chamber provided with suitable inclosing-walls, its top Walla being formed with an inlet-opening a and its bottom wall c2 with an outlet-opening ai. The opening a is usually arranged in the front extremity of the -top wall a, and is closed by a suitable stopper a4, and the opening a3 is preferably arranged in the front end of the bottom wall a2. A receiving-chamber B is arranged beneath the front extremity of the chamber A for receiving the dusting material fed through the openinga, and is preferably formed of less length and size than the chamber A, so as to contain a milch smaller amount than the chamber A. The chamberB is provided with an inlet-opening b in the rear end of its outer side wall and an outlet-opening b in its front wall, and a discharge-tube b2,

'from the opening b.'

provided with a flaring outer end, projects The bottom wall b3 of the chamberl B is preferably removable for permitting access to said chamber and examination and repair of the cutoff and its operating connection, presentlydescribed. To fa cilitat'e removal of the wall b3 its longitudinal edges are providedwith shoulders b4, engaged with corresponding shoulders b5.

O is a blower arranged at one side of the chambers A B and provided with a movable f wall c and flexible top, bottom, and rear walls c c2 c3. The front end of the movable wall c is arranged in close proximity to the adjacent side walls of the chambers A B, and is hinged by any suitable device, as a exible strip c4. The rear end of the wall c is provided with a hand-engaging piece c5, and the opposite side wall 0,5 of the.chamber A is provided with a similar hand-engaging piece o6. As the user of my invention forces the hand-piece c5 a6 together, for collapsing the blower O, its movable wall, c is forced toward the adjacent walls of the chambers A Band its iexible top and bottom walls assume the position indicated by dotted lines at Fig. 2. As the blower C is collapsed the airtherein is forced through the opening b into the rear end of the receiving-chamber B and forcibly ejects the dusting material therein through the outlet-opening b and the discharge-tube b2.

D is a cut-off for facilitating the operation of my improved duster, and, as best illustrated at Fig. 3, this cut-off is pivoted at d to the top wall of the chamber B, and is so arranged that one extremity d is normally beneath the opening a3, as clearly seen at Figs. 2 and 4, for preventing passage of the dusting material from the chamber A through the opening as into the chamber B. The cut-off D is rocked into and out of its normal position by a suitable connection d2, having one end hinged to the opposite extremity of said cutoff and its other end hinged at d3 to the movable wall c. The connection d2 preferably consists of opposite sections adj ustably secured. together in any desired manner, as by a fastening-screw d4; but it may consist of a single piece if no lengthwise adjustment thereof is desired. The movement of the cut-off D from its normal position effected by the outward movement of the wall c disturbs thednsting material immediately above said cut-oitl and facilitates the entrance of said material into the chamber B.

The operation of my duster will be readily understood upon reference to the foregoing description and the accompanying drawings, and it is obvious that the same is readily manufactured and repaired and is capable of continued and practical operation.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is,-l

l. In aduster, the combination of a supply chamber, a receiving chamber connected to the supply chamber, a cutoff for regulating the passage of the dusting material to the receiving chamber, and a blower for ejecting the dusting material from the receiving chamber having a movable side wall connected to the cutoff, substantially as and for the pur pose described.

2. In aduster,the combination of a supply chamber, a receiving chamber connected to the supply chamber, a cutoff for regulating the passage of the dusting material to the receiving chamber, a blower for ejecting the dusting material from the receiving,r chamber provided with a movable side wall, and an adjustable connection between the cutoff and the movable side Wall, substantially as and for the purpose set forth.

3. In a duster, the combination of a supply chamber provided with a discharge opening in the front end of its lower Wall, a receiving chamber arranged beneath the frontextremity of the supply chamber and provided with a removable bottom wall, said receiving chamber being formed of less length and size than the supply chamber and provided with a discharge opening in its front end and an inlet opening in the rear end of its side wall, a pivoted cutoff supported in the receiving chamber and having one extremity arranged normally beneath the opening in the lower Wall of the supply chamber for closing` the same, a blower arranged at one side of the former chambers for forcing a discharge current of air through the inlet opening of the receiving chamber, and formed with a movable outer sidewall and fiexible top, bottom and rear walls, and a connection between the opposite extremity of the cutoff and the movable side wall, substantially as and for the purpose described.

In testimony whereof I have hereunto signed my name, in the presence of two at` testing witnesses, at Pulaski, in the county of Oswego, in the State of New York, this 13th day of March, 1895.

CHARLES LEROY.
